===========

Although you provide only the URL, OkHttp plans its connection to your webserver using three types: URL, Address, and Route.

### [URLs](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-http-url/)

URLs (like `https://github.com/square/okhttp`) are fundamental to HTTP and the Internet. In addition to being a universal, decentralized naming scheme for everything on the web, they also specify how to access web resources.

URLs are abstract:

            if (StringUtil.isNotBlank(getIncludedDocUrls())) {
                final List<Pattern> urlPatterList = new ArrayList<>();
                final String[] urls = getIncludedDocUrls().split("[\r\n]");
                for (final String u : urls) {
                    final String v = systemHelper.normalizeConfigPath(u);
                    if (StringUtil.isNotBlank(v)) {

        Set<String> packages = new LinkedHashSet<>();

        try {
            Enumeration<URL> urls = loader.getResources(BUILDER.getExtensionDescriptorLocation());
            while (urls.hasMoreElements()) {

                try (InputStream is = urls.nextElement().openStream()) {
                    ExtensionDescriptor descriptor = BUILDER.build(is);
